SCR Systems Require Level Detection Capabilities
SCR systems have created a paradigm shift for vehicle operation. Put simply, the way vehicles cannot function when their fuel tanks are empty is the same way they also cannot function when their Adblue tanks are empty.
The ability to detect the presence or absence of AdBlue in the storage tank is, therefore, critical to the SCR system’s performance and to ensure compliance.
AdBlue level sensors take away any guesswork. These sensors determine the level of fluid in the tank and relay the information to the control unit. Depending on the input, the control unit:
- allows the vehicle to operate normally,
- returns a warning message to the driver in a visual (gauge) or audible alert, or
- limits the vehicle’s performance, thereby stalling operation or reducing productivity until the AdBlue tank is topped up.
Since AdBlue consumption in heavy-duty vehicles is about 3-5% of total fuel consumption levels, a simple guideline is for users to fill up their AdBlue tank whenever the diesel tank is filled. And where there are no AdBlue filling stations, it’s recommended to carry along a top-up container.
The AdBlue level sensor works by sending a signal to the vehicle’s engine control module (ECM) or AdBlue control unit, which then displays the level of AdBlue fluid on the vehicle’s dashboard. The sensor typically uses ultrasonic technology to measure the level of AdBlue fluid, by emitting sound waves that bounce off the surface of the fluid and are then detected by the sensor.
AdBlue is a diesel engine exhaust fluid that is used to reduce the emissions of nitrogen oxides (NOx) from diesel engines. The AdBlue level sensor is a component of the AdBlue system that is used to measure the level of AdBlue fluid in the vehicle’s AdBlue tank.
The AdBlue level sensor is an important component of the AdBlue system, as it ensures that the vehicle always has an adequate supply of AdBlue fluid. If the AdBlue level becomes too low, the vehicle’s ECM may limit the vehicle’s performance or even prevent it from starting, until the AdBlue tank is refilled.
An adblue level sensor is a device that is used to measure the level of adblue (also known as diesel exhaust fluid or DEF) in a vehicle’s adblue tank. Adblue is a solution of urea and water that is injected into the exhaust system of diesel engines to reduce harmful emissions.
The adblue level sensor typically consists of a float that sits on top of the adblue fluid in the tank and a sensor that measures the position of the float. As the level of adblue in the tank changes, the position of the float changes, which is detected by the sensor. This information is then sent to the vehicle’s computer system, which uses it to determine how much adblue is left in the tank and when it needs to be refilled.
The adblue level sensor is an important component of the adblue system, as it allows the vehicle to operate efficiently and meet emissions regulations. If the adblue level sensor fails or becomes inaccurate, it can cause the vehicle to experience performance issues and potentially fail emissions tests.
